Abstract: The paper records the occurrence of well-preserved planktic foraminifera from Vridhachalam area of the Cauvery Basin; Tamil Nadu; south India. Preliminary analysis of the samples from Vridhachalam area shows abundant well preserved planktic foraminifera belonging to Parasubbotina; Subbotina; Igorina; Acarinina and Morozovell. ; Seventeen planktic foraminiferal species recorded in all the outcrop sections indicate Palaeocene early Eocene age. Reworked late Maastrichtian planktic foraminiferal species (Hedbergella holmdelensis; Globotruncana arca; and Globotruncana sp. ; Rugoglobigerina rugosa are common suggesting erosion of uplifted Cretaceous sediments. Species are illustrated based on SEM microphotographs.
